Method to enable the prevention of cache thrashing on memory management unit (MMU)-less hypervisor systems

A hypervisor system, comprising:

• a virtual machine (VM) circuit comprising a plurality of VMs, wherein each VM of the plurality of VMs is configured to perform one or more operations associated with the hypervisor system;
• and
• a cache circuit comprising a cache memory circuit, the cache memory circuit comprising:
• a plurality of cachelines, wherein each cacheline is configured to store data associated with one or more virtual machines (VMs) of the plurality of VMs associated with the hypervisor system;
• and
• a plurality of tag array entries respectively associated with the plurality of cachelines, wherein each tag array entry of the plurality of tag array entries comprises:
• a tag field configured to store a tag identifier (ID) that identifies an address of a main memory circuit to which a data stored in a corresponding cacheline is associated;
• and
• a VM tag field configured to store a VM ID associated with a VM to which the data stored in the corresponding cacheline is associated.
